摘要
采用流固耦合的计算方法对带牵顶伞的主伞的充气过程进行了数值模拟,得到了主伞伞衣充气过程外形变化情况,并与试验结果进行了对比;对牵顶伞阻力系数的变化进行了分析,给出了适合工程估算的牵顶伞阻力系数公式。
Based on the method of fluid-structure coupling,numerical simulation has been carried out in the inflation process for main parachute with an apex grogue,and the canopy deformation during inflation can be obtained,which was compared with the actual situation.Drag coefficient of variation for apex grogue is analyzed,and drag coefficient formula estimated for engineering is presented.
